Reforged in Hellfire – Best in Slot Reforged in Hellfire is Mortenax Blade’s signature Light Cone, and it’s built specifically around his kit. At Superimposition 1, it increases the wearer’s Max HP by 30% and regenerates a fixed 20 Energy at the start of the wearer’s turn, once per wave. That Energy refund is what lets Mortenax Blade reliably open a fight with his Ultimate already charged.

After Mortenax Blade lands a Skill Attack while wearing it, the target is afflicted with the “Purgatory” state for 2 turns. While Purgatory is active, CRIT DMG taken by that target increases by 30%, and CRIT DMG taken from Mortenax Blade specifically increases by an additional 30%. That’s a real damage multiplier stacked directly onto his own hits, well beyond a generic team buff.

The honest call here is that Reforged in Hellfire isn’t technically a must-pul l. His alternatives below cover most of the same ground, and the gap between his signature and his best F2P pick isn’t as wide as it is for some other 5-star debuffers. Still, if you already have it or plan to pull for Mortenax Blade anyway, Reforged in Hellfire remains his best general Light Cone pick.
